The Claim
Twenty-eight days of combined beta-alanine and creatine monohydrate supplementation in healthy young men has no statistically significant effect on aerobic power, ventilatory threshold, lactate threshold, or time to exhaustion compared to placebo, despite within-group improvements that are attributable to practice effects rather than physiological adaptation.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking beta-alanine and creatine together for 28 days does not improve aerobic performance metrics such as endurance, breathing thresholds, or time to exhaustion in healthy young men, compared to a placebo.
See the scientific wording
Twenty-eight days of combined beta-alanine and creatine monohydrate supplementation in healthy young men does not significantly improve aerobic power, ventilatory threshold, lactate threshold, or time to exhaustion compared to placebo, despite observed within-group improvements in the supplemented group that may reflect practice effects rather than physiological adaptation.
The body does not increase its ability to use oxygen, clear lactate, or sustain high-intensity effort longer because beta-alanine and creatine do not change the muscles' energy production or buffering systems in a way that affects aerobic performance.
What the research says
1 studyPeople took a mix of two supplements for four weeks and then did a bike test. They didn’t do any better than people who took a sugar pill — any small improvements were probably just because they got better at taking the test, not because the supplements worked.
